My invention relates to a method of and means for producing glossy or lustrousfabrics as a substitute for glac-thread fabrics or fabrics of polished yarn.

The warp-threads .of the known glacthread fabrics, which are employed as linings as well as for other purposes, consist of glacthreads whichare produced in the following manner:- Y

The raw yarn is reeled on two-lease reels. Hereafter the same is dyed and dressed and made'glossv or lustrousby ineans of rotating brushes. The threads a then reeled and warped and the warp lis-"fin shedfin a known manner; It is obvious that'tli-is'xprocedure is very cumbersome and expensive and calls for a number of special machines. According to my invention fabrics are produced which are a satisfactory substitute 2?! for glac-thread fabrics, but which are produced in a more simple and less expensive manner. The finished fabric is soaked with a dressing means andv subsequently the fabric under tension is treated on one side or on both sides by means of rapidly operating lustring or polishing tools, particularly brushes, until the material shows the character of a glacthread fabric. The fabric to be treated in this manner maybe manufactured either of coloured yarns or it can be dyed as a whole before the lustring or polishing is done.

Thus according to the new method all special working operations for producing the glac-thread are dispensed with. The manup facture of the lustrous fabric which is a satisfactory substitute for the known glac-thread fabrics, because only a simple subsequent treatment of a finished fabric is necessary to I be carried out, which is far more simple than the particular process above referred to and which is necessary for producing glacthreads and warps thereof.

Polishing of the finished fabric is preferably performed by means of brush-rollers,

" which are arranged transversely to the longitudinal direction of the fabric, the latter under tension being pulled over the brushrollers in a longitudinal direction. Thus the brush-rollers rotate in the direction of the movement of the fabric in such a manner that 100,360, and in Austria August 1, 1925.

the circumferential speed of the brush-rollers at the contacting places is multiplied a number of times more than the speed by which the fabric is drawn past the brushes. However it is also possible to allow the brushes to 55 rot-ate inthe opposite direction.

In order to produce the lustre on the fabric llis necessary to first glue the fibres of the threads, which the fabric consists of, to the threads themselves, this being accomplished 00 by submitting the fabric soaked with a sticky dressing means to a brushing action. Then the fabric has again to be treated with brufihcsin order to prodce the highly lustrous surface, the gluing of the fibres serving only to smooth the surface of the fabric, thus preparing it for the subsequent lustring.

The lustre itself can be produced only by submitting the fabric to an intensive brushing for a suitably long time, and if it is desired to continuously move the fabric over the rotating brushes in order to obtain a continuous process, a considerable number of such rotating brushes is necessary.

One mode of carrying out my invention is illustrated by way of example in the accompanying drawings in which Figure 1 shows in elevation and Figure 2 in plan view a machine constructed according to the invention.

- At one end of a frame 1 is mounted a beam 2 from which the fabric 3 is wound off, and at the other end of the frame 1 is'located a beam 4 on which the fabric is wound up after having travelled through the machine. The beam 4 is driven by means of a chain 5, which passes over a chainwheel 6, mounted on a shaft 7. The latter carries a Worm-wheel 8, which is driven by a worm 9, the latter being mounted on a shaft 10 driven by a shaft 12 by means of a belt 11.

The frame 1 carries further a number of guide-rollers 13, atrough 15 which contains the dressingliquid which for examplemay be composed of the following proportions of quantities, 80 l. of water, 10 kg. of wheat starch,

(g. of paraffin, A,, l. of Turkey red oil,

l. of glycerine, and a roller 16, between which and a roller 17, arranged above the roller 16, pass the fabric 3 after having been wound off mounted in the frame 1 in such a manner that the fabric 3 passes in zigza over these rollers and moreover a number of rush-rollers 21 is arranged one after the other in such a manner as to allow the fabric to come into contact with each brush-roller, in'two laces. But it.

may also be that the brush-r0 ers are so arranged as to come into contact with the fabric onl in one place. Y

The uide-rollers 20 may be adjustably mounte in a vertical direction as illustrated for the rollers 20 shown in Figure 1 at the left end of the lustring portion. The bearings of these'rollers 20 may be adjusted in a vertical direction in their supports 24 and 25 respectively by means of vertical screws 22, in order to vary the tension of the fabric as re uired. Adjusting and tentering devices of t is kind may be provided for all'the guiderollers 20 or for some rollers only.

After leaving the last guide-roller 20, the fabric 3 passes over resistance-rollers 26, 27 and 28, the roller 27 being mounted on the shaft 7, which as above mentioned is driven by the worm-wheel 9. From here the fabric 3 proceeds to a drying-box 29 where it passes over and down over rollers 30, 31, 32, 33 and 34 in order to travel for a considerable time through the dryingv box. A coil-pipe 35 .is arranged in the lower part of the drying box and is supplied with steam b means of a tube 36, whereby the interior of t e drying box 29 is heated and the fabric is completely dried.

The vapours escaping from the fabric leave the drying box through a chimney 37.

.From the drying box the fabric 3 passes over a guide-roller 38 to the beam 4, where it is wound up.

The roller 16 of the dressing trough 15 is mounted on a shaft 39 carrying a worm-wheel 40 which is driven by a worm 41, arranged on the shaft 10, which carries also the worm 9. Therefore the roller 16 of the dressing trough is driven in accordance with the guide-roller 27.as well as with the beam 4, whereby the required tentering condition of the fabric 3 is secured, during the whole travel through the machine.

The brush-rollers 21 are driven in groups by shafts 42 and 43, these again being driven by a motor which drives also the shaft 12.

By passing between the rollers 16 and 17 the fa ric is soaked with the dressing liquid and immediately afterwards is subjected to the action of the brush-rollers. In consequence of their high speed of rotation, these brush-rollers intensively act upon the continuously travelling fabric in such a manner that not only the dressing liquid is uniformly distributed over the surface of the fabric and the fibres projecting from the threads of the fabric are glued down, but also the desired highly lustrous surface is gradually produce The brushes operate on the fabric only be-v tween each'two guide-rollers 20 so that the contact between the brushes and the fabric is a resilient one, this securing the advantage of the bristlesof the brushes penetrating also into the depths of depressions of the fabric. Thereby a lustrous condition is produced not only on the uppermost parts of the threads of the fabric, but also in the deeper parts of the surface.

Obviously the present invention is not limited to the illustrated embodiment as the same may be varied without departing from the spirit of the invention. For instance brush-rollers may be arranged also in such a manner that they operate on the upper surface of the fabric. If desired also heated rollers or heated pairs of rollers may be arranged between the successive brushes.

What I claim as my invention is 1. A machine for manufacturing glac .fabric comprising a frame, a beam for winding oil the fabric to be treated and a beam for winding up the treated fabric, a plurality of guiding rollers for the fabric arranged 1n staggered relationship between said beams, a trough adapted .to contain a dressingsubstance, means for applying said substance to the fabric, and a plurality of successive rapidly driven rotating brushingrollers arranged with their shafts transversely disposed 'with respect to the direction of movement of the fabric, said brushingrollers being adapted to contact with said fabric between said guiding rollers.
